Title: Shaft-wall seal with elastomerically protected reinforcement rings
Inventor: KLEIN NORBERT
IPC: F16J15/3224
Filed: 1993-01-20
Abstract: Seal arrangement for the sealing of a shaft extending through a bore in a wall includes a radially sealing seal ring which has at least one sealing lip of elastomeric material for sealingly engaging the shaft along its circumference, an L-shaped first stiffening ring having a radially outwardly directed first leg and an axially extending second leg and an anti-friction bearing positioned in radial direction between the shaft and the second leg.  The sealing lip is fixed to the first leg of the first stiffening ring.  The second leg is enclosed by elastomeric material at least at its axial end and sealingly engages the bore wall under radial pretension.  The inner ring of the anti-friction bearing is supported on the shaft and the outer ring is supported on the coated portion of the second leg.  The seal arrangement has improved operating characteristics over a long service period, improves the guiding of the shaft in the region of the seal and provides for the insulation/damping of vibrations of the rotating shaft during use.

Abstract: (60-SD-581) METHOD FOR PRODUCING UNIFORM            CYLINDRICAL TUBES OF CVD DIAMOND     Abstract of the Disclosure The present invention provides a method for farming uniform CVD diamond coatings on a substrate wherein diamond is deposited on a plurality of substrates which are rotated in unison during the coating process to provide for more uniform radial growth.  An advantageous substrate is a wire which can be coated with a layer of CVD diamond for making components in water-jet cutting apparatus, wire-drawing dies, or other tubular articles when the wire is separated from the resulting diamond tube.  Identical tubes with higher uniformity in wall thickness are among the products which can be obtained. In addition, tubes having a uniform particle size distribution along their wall thickness which supports columnar diamond growth are also provided.

Title: Method and apparatus for transmission and reception of a digital television signal using multicarrier modulation
Inventor: HULYALKAR SAMIR N
IPC: H04N5/44
Filed: 1993-03-17
Abstract: A method and apparatus for modulating and demodulating an MCM television signal is described which is particularly useful in proposed "simulcast" HDTV terrestrial broadcasting. The MCM spectrum of the television signal is shaped using weighting coefficients which are derived from either an idealized NTSC signal or an actual NTSC co-channel signal. These coefficients are used to shape the respective MCM carriers to provide an energy distribution in the MCM signal which provides greater degree of robustness with a minimum degree of co-channel interference to and from an NTSC co-channel signal. The instant invention further takes advantage of the interference characteristics of composite television signals described above, to position the placement of the MCM carriers in frequency, to minimize interference with an NTSC co-channel signal. Several methods of deriving the weighting coefficients are described including an adaptive approach whereby the characteristics of the interfering NTSC transmission are received and the instantaneous NTSC spectrum calculated therefrom and weighting coefficients assigned accordingly. These coefficients can be transmitted to a receiver to update its coefficient table.

Title: Frequency dependent optical isolator
Inventor: BARNARD CHRIS
IPC: H04B10/17
Filed: 1993-04-02
Abstract: A frequency dependent optical isolator is provided which allows two signals transmitted on a single optical fiber to be isolated in dependence upon their frequencies. A signal having a frequency f1 propagates through the isolator in one direction from a first input/output port to a second input/output port and is prevented from propagating in the reverse direction. A signal having a frequency f2 propagates through the isolator from the second input port to the first input port and is prevented from propagating in the reverse direction. After either of the signals propagates through the isolator from one input/output port to the other, the isolator prevents the respective signal from traveling backwards in a reverse direction through the isolator. The frequency dependent isolator may be used with an amplifier or may amplify one or more of the signals propagating through.

Title: Horizontal line counter stabilization in a video receiver
Inventor: TULTS JURI
IPC: H04N7/087
Filed: 1992-06-15
Abstract: In a system for identifying specific horizontal lines of video that are included in a video signal, a horizontal tine counter (100) is cleared to indicate the beginning of a vertical interval by a reset signal (VERDEL) derived from a vertical sync signal (VER). The line counter is clocked by a signal (HOR) at the horizontal sync rate that is derived from a harmonic (N-FH) of the horizontal sync signal. The relative phase shift between the reset and clock signals for the horizontal line counter is mea-sured (105, 120). The measured phase shift is used as an input to a variable phase shifter (110) to adjust the phasing between the horizontal line counter control signals and the original sync signals. The phase adjustment permits significantly decrea-sing the sensitivity of the horizontal line counter to jitter of vertical sync.
